Aiming to improve on the default design, the Leofoto CF-04 is a replacement for the original foot supplied with the Canon EF 400mm f/2.8L IS III USM, EF 600mm f/4L IS III USM, and EF 800mm f/5.6L IS USM lenses. This aluminum support with built-in Arca-type dovetail mounts features both a 1/4"-20 and 3/8"-16 receivers as well as a QD (Quick Disconnect) socket for quickly attaching a compatible strap or sling. Two M3 screws are included for use as optional safety stops.
